Thalassinoides
Thalassinoides Ehrenberg, 1944 DESCRIPTION: Three-dimensional boxwork of branched cylindrical burrows interconnected by vertical shafts. BEHAVIOR(S): Deposit-feeding and dwelling. ENVIRONMENTAL SETTINGS: Shallow marine and deep marine turbidites. POSSIBLE TRACEMAKERS: Crustaceans GEOLOGIC RANGE: Cambrian-recent …Several crustaceans producing Thalassinoides-like burrows are known to follow variable nutrition modes, from suspension or filter to deposit feeding (e.g., Gingras et al., 2008; Pervesler and Uchman, 2009). The draught-fill and the sandy nature of fill of the tubular tidalites indicate that burrows were passively ventilated and hence, currents ...La evolución del océano de Tetis.
